67 Front Bench seat re-upholster

[L78Kiwi]

Hello, This out of my 67 L78 I am restoring and I need to know which foam kit to use.

As the backs of the seat are the same for the bucket seats, I am wondering if I need a bucket as well as bench seat kit. Classic list a bench seat foam kit but it appears to be generic to a variety of years and makes.....hence is the question of wether I need the other kit also for bucket seats

Any help would be appreciated
